Display device

A display device, comprising:

• a first substrate;
• a second substrate opposite to the first substrate;
• plural scan lines disposed on the first substrate and extending along a first direction;
• plural data lines disposed on the first substrate and extending along a second direction, wherein at least one pixel region is defined by the scan lines and the data lines, and the first direction and the second direction are different;
• a common electrode disposed in the pixel region;
• a metal line electrically connecting to the common electrode and extending along the first direction, wherein the metal line has a first portion and a second portion, the second portion overlaps one of the data lines, the first portion is a region of the metal line excluding the second portion, and the first portion partially overlaps the common electrode;
• and
• a black matrix layer disposed on the second substrate, wherein the black matrix layer has a light shielding region extending along the first direction, and the light shielding region covers the metal line;
• wherein the first portion has a first maximum width along the second direction, the second portion has a second maximum width along the second direction, and the first maximum width is greater than the second maximum width,
• wherein the metal lines has a metal edge closest to a shielding edge of the light shielding region, the shielding edge extends along the first direction, and a distance between the shielding edge and the metal edge is between 0 μm and the first maximum width.
